DISH-WASHING MACHINE.

To all whom it may concern:

crease the e Be it. known that I, PATRICK T. DUNN, a citizenof theUnited States, residing at Cedar Rapids, in the countyofqLinn' and Stateof Iowa, have invented certain new and useful Improvements inDish-Washing Machines, of which the following is a specification.

This invention relates to improvements in apparatus for washing dishes,and for like purposes, and has for one of its objects to im fore theconstruction and iniciency and utility of devices of this character.

.Another object of the invention is to provide a-de'vice of thischaracter whereby the dishes may be caused to pass through the.

cleansing'liquid and agitated therein and i then caused to pass througha rinsing liquid and subjected to heat for drying the same. With theseand other objects in view, the

"invention consists, in certain novel features of construction, ashereinafter shown and described and then specifically pointed out in theclaims; and in the drawings illus- -trative otthe preferredembodim'entbf the 3 vf-porting. cage or basket;

The improved device comlprises 'coacting receptacles, one for-thecleansing liquid and one for the rinsing liquid, and a basket of novelconstruction within and upon which the dishes are supported and mountedfor rotation first Within the receptacle contain-' ingthe cleansingliquid and then in the re-" ceptacle containing therinsin liquid, and

means for a plying heat to t 'e receptacle containingt e cleansingliquid, and means 'forapplyin'g heat to the vessel containing therinsing liquid, the latter heat .impart ing medium beinglikewisc adaptedto dry the dishes t r being rinsed.

may be closed when the improve Specification of Letters Patent. PatentedOct. 23; 191 Application filed May 7, 917. Serial 'No. 186,993. I

The receptacles for'the cleansing liquid and the rinsing liquid arepreferably arranged side by side, or in convenient position to' enablethe basket containing the dishes to be readily. inserted in either oneof the receptacles. The receptacles will preferably bearrangedin'connection with an ordinary kitchen table, but notnecessarily limited toany specific form oftable '5' or other support.For the purpose. of illlu' tration the improved device is shown a-.

a suitable closure, a portion 'of which is shown at 14 andhingedlyiunited to the top 10 at 15. this means the o eni iig 13 deviceis not in use. i

' -The' receptaole liqnid is' frepresented atlti, while theq'eceptaclefor 5 the rinsing liquid is re seated-M17, the receptacles being preerably.

"cute with the opening. 13. The'receptacles are-greater in depththan'half'of a circle and are provided? with upwardl' openingseat'soneof Which isrepresente at '19, to

.receive trunnionss. on the fdisl supporting aimed. The rebasket, ashereinafter e required size but ceptacles may be or an .for an ordinarysi-zed' d vi'ce the radius of.100

the curved portion'of tfe receptaclewill be about seven inches, is thetotal height will be about nine inc es, but these dimensions may bevaried a required. At their upper edges thememb rs'16'17 are formed withlateral flanges 2 to bear beneath the top 10 and over theiupper edge ofthe di-' vision member 118 as shown in Fig. 1,;and attached to thetabletop and to the division member by;- suitable fastening devices suchas screws or nails. At one side the skirt member 12 of the table isprovided relatively large openings, one of which is air of the shown at21 opposite one sockets 19, to enable an operating crank to be insertedto engage the dish supporting 5 basket and rotate the same, ashereinafter explained. I

Suspended beneath the receptacle 16 is a burner device indicated at 22,while a similarburner device is supported beneath the receptacle 17.,For the purpose of illustration the burner device is shownin the form ofa tube having a plurality of gas orifices 23 and each burner deviceprovided with a controlling valve, one of which is represented at 24:.The burner devices are shown suspended from theskirt member 12 of thetable by hangers Deflector plates 2627 depend respectively from thereceptacles 1617,""to confine the flames and heat 20 units rising fromthe burners and causing them to impinge with greater force against thereceptacles and thus impart the necessary. heat to the cleansing andrinsing liquids. The receptacles 16-17 are precisely alike and eitherone thus ,adapted to receive the cleansing liquid or the rinsing liquid.

The basket or container for the dishes to be washed comprises an oblongmetal frame represented as awhole at 28 and forming" a band or supportat the upper edge of the basket. Relatively long U-shaped frames 29-3 0are provided and extend longitudinally of the lower corners ofthe basketand obliquely across the ends of, the same and cross centrally of. thends of the basket.

strong andrigid supporting frame for the' walls of the basket which areformed of relatively heavy coarsewire screen material indicated at 33,the screen material being riveted or otherwise secured to the framemembers 28-29-T3Q A closure is provided p for the open side ofthcbas'ket and comprises an inclosing frame represented "at .34, theframe-members forming a support'for the screen material 33 of thetop.Thus the sides, bottom and top and the ends of the basket are formedprincipally of the screen material and suitablyv supported-by.

' ithcfri'ime members 2829-30 andfi l. The 65' f1'a.Ine member 34: ofthe top is hingedly "united at 35 to the frame 28 at one side'and,

provided with short sections'of chain 36 at the other side, the latteradapted to. be engaged by one of its links beneath checklike device 37extending from the frame 28. Extending through the members 2930dttheitcrossing poi'iits are combined clamp devices and trunnions shownmore particulaifly in Fig. 2'. lhe apertures'through the 5 i f j'9-30fat1thei'r crossed points are ings in the frame members, as shown at38.

The combined clamp and trunnion members are threaded to receive clampnuts 3940 at opposite sides of the members 2 930 so thatthe combinedtrunnion and clamp members are firmly united to the basket frames. Thecombined clamping and trunnion memhers-are each provided with a bearing41 to engage in the sockets 19 as shown in Fig. 2, and one of thecombincd'elampin'g andtrunnion members is extended and. formed square,as shown at 42 to receive a turning .crank whereby the basket mayberotated. The squared portions l2 of the combined clamping and trunnionmembers are adapted to extend through the openings 21 in the skirtmember 12 of the table, as shown in Fig. 2. Thus when the basket deviceis mounted for rotation in the receptacle 16 the squared portion .12will extend through. one ofthe openings 21 and then when the basketdevice is mounted for rotation. in the other receptacle 17 the squaredportion 42 will extend through the other opening 21. By this means thebasket device may be rotated within either one of the receptacles.

Attached to the sides, bottom and top of the basket are'supporting wiresindicated-at 43 in position to support dishes of plate-like ,form,represented at 44, as shown more particularly in Figs. 1 and Generallythe basket device will belarge enough to hold two plates upon each side,bottom and top,

* and thewire supports 43 will be connected at the ends as shown at 45x0the wire screen material 33 a d likewise at an intermediate point, as shn at 46. Onev of the holding devices 46at each side, bottom and top willbe in the form of a movable hook, so that after the ishes' are locatedin position a suflicient strain may be applied. to one of the holdingwires to hold the dishes in position and prevent their displacement whenthe basket is rotated. The remaining dishes to. be washed, such assaucers, tea-cups and the like will be located within the basket, andmaybe arranged in any suitable manner. To enable the smallerdi-shes,-such as saucers tea-cups and the like to be held in p'osition'aplurality of-diaphragmlike devices, one oi a plurality of ockets orcompartments in A when the baskefis rotated.
